Antioxidant Activity of Some Dried Autochthonous Albanian Fig (Ficus carica) Cultivars

Abstract

ABSTRACT

 

The aim of this paper is to evaluate the phytochemical character and total antioxidant capacity of sun-dried autochthonous fig cultivars commercially most known in Albania. Samples of five fig cultivars such as Roshnik, Rotllar, Bishtgjati, Melacak, and Perdhikuli, respectively cultivated in Berat, Tirana, Elbasan, Shkodra and Himara in Albania, were taken under consideration. The methanol extracts of dried fruits of each autochthonous fig cultivars were analysed to determine their total polyphenols content, anthocyanin and flavonoids content; the antioxidant activity using DPPH (1,1-diphenyl-2-picryl hydrazyl) and ABTS (2,2'-azinobis- (3-ethylbenzothiazoline-6-sulfonic acid), was evaluated too. The data obtained showed that the samples had total polyphenols content varied from 45.24-160.42 GAE mg/100 g DW of sample, the anthocyanin from 0.0-5.32 mg cyn-3-glu/100 g DW of the sample and flavonoids from 18.31-36.95 mg (+) catechin/100 g DW of the sample. Antioxidant activity expressed as DPPH varied from 387-825 mol TE/100 g DW of sample, while ABTS values ranged from 309-886 mol AAE/100 g DW of sample.

The results of this study are the first data published for autochthonous Albanian fig cultivars, and showed that the selected dried figs are a good source of antioxidants. There were seen significant differences between dark and light fig cultivars in total polyphenolic, total flavonoid, total anthocyanin content, and antioxidant capacity. The data obtained are similar to other studies about sun dried figs.
